This is the worst game glitch Ive ever seen

As I was fishing, the game decided to select my ruthless Paladins hammer (great late game weapon) as bait, and then spent it, while I get nothing. Ive now lost months of work, and have to redo many things. Not only that, but I got superior The Axe (another late game tool) after countless times fighting Plantera, and after one swing, it disappears. Thanks game
